Abstract
INTRODUCTION: This study evaluated the efficacy of the interleukin-17A inhibitor secukinumab in patients with oligoarticular psoriatic arthritis (PsA).
METHODS: A total of 84 patients with oligoarticular PsA, defined as 1-4 tender joints and 1-4 swollen joints, were pooled from the FUTURE 2-5 and MAXIMISE trials (NCT01752634, NCT01989468, NCT02294227, NCT02404350, and NCT02721966). Patients were grouped by treatment received at week 12 (secukinumab 300 mg, secukinumab 150 mg, or placebo) and week 52 (any secukinumab 300 mg or any secukinumab 150 mg). Efficacy was assessed by the proportion of patients achieving selected clinical outcomes. The predictors of Disease Activity index for Psoriatic Arthritis (DAPSA) responses at weeks 12 and 52 were identified by logistic regression analysis.
RESULTS: Secukinumab treatment resulted in greater achievement of DAPSA-based low disease activity (LDA), DAPSA-based remission (REM), DAPSA50, and DAPSA75 than placebo at week 12, with improvements sustained or further increased through week 52. LDA or REM was achieved at week 52 by more than 90% of patients who received either secukinumab dose, although secukinumab 300 mg resulted in the highest achievement of the stringent DAPSA75 and DAPSA REM outcomes. At week 12, younger age was associated with DAPSA LDA or REM and DAPSA50, while lower baseline swollen joint count was associated with DAPSA REM. No predictors were identified at week 52. The safety profile was consistent with the full study populations.
CONCLUSION: Secukinumab demonstrated efficacy vs placebo across several outcome measures in patients with oligoarticular PsA at week 12, with sustained or improved responses through week 52.
